What is an umbilical hernia? An umbilical hernia is a bulge through the abdominal muscles in the area of the navel (belly button). The hernia may contain tissue from the abdomen, part of an organ (such as the intestine), or fluid.
Iliac crest contusion occurs due to bleeding of abdominal muscles and swelling. This can cause excruciating pain when the person tries to move his hip region. Bleeding can occur on the periosteum region of the bone resulting in inflammation and the muscles of the iliac crest would develop spasms.
It is also not tender upon palpation. It is also NOT on both sides, just the right, so I do not think it fits in with Iliact Crest syndrome/back pain either. I used to have a similar pain in my right hip joint that I no longer have. This Iliac Crest pain seems to have taken over that one, if that makes sense. I DO have a herniated L4, L5, but this started before I herniated the discs (I remember the exact moment I bent over and the discs ripped). I do have slight scoliosis.
